General Information
Class 8502 Type W non-reversing vacuum
contactors are a new addition to the Square D line
of contactors. These contactors are used to switch
capacitors, transformers and electric motors
where overload protection is separately provided.
Type W vacuum contactors are designed for
operation at 600 Volts, 50/60 Hertz.
By design, these contactors are well suited to
heavy-duty applications in harsh environments.
The power contacts are sealed in ceramic tubes,
called vacuum interrupters or vacuum bottles,
where the air has been evacuated. Arc quenchers
are not required because any arc formed between
opening contacts is not sustained due to the
presence of the vacuum. The arc is extinguished
when the current crosses zero after the contacts
are opened, therefore the arc typically does not
survive more than one half cycle. There is one
vacuum interrupter or bottle per pole, therefore a
three pole contactor has three vacuum
interrupters or bottles. The power contacts are not
affected by ambient conditions or contamination.
This provides for long life and reliable operation in
harsh applications.

Altitude
The vacuum contactor is designed to tolerate
normal barometric pressure variances up to 6600
feet above sea level. If the contactor is to be used
above 6600 feet above sea level, please consult
the factory.
Termination Means
The Size 4 vacuum contactor is supplied with line
and load side lugs
contactors are supplied without line and load side
lugs. Class 9999 Type LUW5 and LUW6 lug kits
are available for the Size 5 and 6 contactors.
These kits include six lugs and the necessary
mounting hardware.
Auxiliary Contacts
An auxiliary contact block, Class 9999 Type
WX11, with one normally-open contact and
normally-closed contact is used with the Size 4, 5
and 6 vacuum contactors.
Auxiliary Contact Units
Auxiliary contact units may be added in the field.
the table below shows the maximum number of
units that may be added to a given size contactor
(in addition to the coil auxiliary contact).
